Generate automatic reports of the bot tasks

[marfox]

As suggested here. For each task, i.e., task 1, task 2, task 3 :

• [ ] keep track of the edited items;
• [ ] build & run an appropriate SPARQL query;
• [ ] fill a Wiki page with the query result.

Example

• bot task: delete invalid identifiers for Discogs;
• goal: report items that have been edited by the bot and don't have a Discogs identifier anymore;
• deleted [Q11898681, Q2048920, Q961940];
• query:

SELECT *
WHERE {
  VALUES ?item { wd:Q11898681 wd:Q2048920 wd:Q961940 }
  FILTER NOT EXISTS { ?item wdt:P1953 ?identifier . }
}
